Java New Features Training
Course 939
3 DAY COURSE

This Java New Features training course provides hands-on experience with lambda expressions introduced in Java and many other language and library changes. Attendees will fully appreciate functional-style programming and the new idioms made possible by lambda expressions that make their code easier to read and understand. The course then explores the Streams API, which lets you write robust code that processes a collection of data in a declarative way. Attendees will fully appreciate what streams are and how they can use them in their programs to process data collections concisely and efficiently.

Java New Features Training Benefits

• In this Java course, you will learn how to:

  • Pass code as parameters to methods using lambda expressions to make your code simpler and easier to understand.
  • The course assumes a background in Java programming with Java 7.
  • Leverage default methods to achieve evolution of interfaces while maintaining compatibility with older code.
  • Process data with Java streams.
  • Take advantage of stream parallel processing to achieve efficiency.
  • Perform asynchronous programming with CompletableFuture.
  • Read and write files using Java NIO.

• Prerequisite

  The course assumes a background in Java programming with Java 7.
